Comparative PCR-based restriction fragment length polymorphism analysis of the plasmid gene orf3 of Chlamydia trachomatis and Chlamydia psittaci

Abstract

The BfaI digestion of PCR-based restriction fragment length polymorphism analysis of the plasmid orf3 of Chlamydia trachomatis and Chlamydia psittaci provided evidence for two distinct restriction patterns, respectively. The nucleotide sequences of orf3 genes confirmed these differences. Serum antibodies against recombinant C. psittaci protein (pgp3) encoded by orf3 were detected both in pigeons with C. psittaci infection and in a human patient with psittacosis. © 2006 Federation of European Microbiological Societies.
